Application'February 19, 1946, Serial No. 648,749.

1 Claim.

This invention relates generally to containers and particularly to containers for liquids and solids requiring special protection or requiring a hermetic seal. I

The main object of this. invention is to provide a convenient form of container which is readily collapsible and which possesses an unusual degree of strength.

The second object is to provide a container of the class described in which an expendable liner is employed rendering it unnecessary to cleanse or sterilize the container between uses thereof.

The third object is to construct a container having a means for carrying a refrigerating compartment therewith.

These and other objects will become more apparent from the specifications following as illustrated in the accompanying drawings in which:

Fig. 1 is an elevation of the container.

Fig. 2 is a plan view of the closure end of the container.

Fig. 3 is an end elevation of the opposite end of the container.

Fig. 4 is a fragmentary section taken through the longitudinal axis of the container.

Fig. 5 is a fragmentary section along the line 55, Fig. 3.

Fig. 6 is a fragmentary section taken along the line 6-6 in Fig. 4.

Fig. '7 is a fragmentary section showing an alternative form of the device in which a dry refrigerant is stored within the container.

Fig. 8 is a perspective View of a clamping ring.

Fig. 9 is a perspective view of the end containing the opening.

Fig. 10 is a perspective view of the end opposite the opening end.

Fig. 11 is a perspective view of one of the col lapsing sections.

Fig. 12 is a perspective view of the threaded and flanged fitting for filling and drawing liquids from the container.

Fig. 13 is a perspective view of the washer or gasket between the threaded flange and the closure.

Fig. 14 is a perspective view of the closure.

Similar numbers of reference refer to the same or similar parts through the several views.

Referring in detail to the drawing there is shown a cylindrical container, the sides of which consist primarily of three sections, each of which is composed of matched boards or staves l5 which are secured to the outer arcuate channels l6 by rivets IT. The staves l5 are secured on the inner side at each end to an inner arcuate channel 3. The intermediate outer channel [9 would not have a. corresponding inner channel. It will be noted that. the inner channels l8,have their ends. 26 protruding somewhat beyond the outermost edge H of the section while the ends 22 are spaced a short distancefrom the edge 23, the purpose of which being, of course, to provide a. definite relationship at the point of union of the sections. 7

The end members of the container are of two sizes. One as shown in Fig. 3, consisting of the inturned channel 24, on the inner side of which is secured a head 25, preferably of metal. Between the sides of the channel 24 is a spacing ring '26 which clamps the head 25 against the channel 24 under the holding action of the rivets 21. It is desirable to provide reinforcing channels 28 across the head 25.

The head 29 shown in Fig. 2 is similar to the one shown in Fig. 3 except that there is provided a rectangular opening 36 surrounded by the angle bar frame 3| whose innermost ends are supported by the elongated angle 32. The closure 34 is secured over the opening 30 by means of the bolts or screws 33.

In Fig. 6 is shown the manner of attaching the fitting 35, whose threaded portion 36 extends through the hole 31 formed in the closure 34. A metal disc 38 is provided for the under side of the flange 39 of the head 35. A nut 41] is placed on the threaded portion 36 and engages the exterior of the closure 34. It will be observed that between the disc 38 and the closure 3d is disposed a liner 4!, the nature of which will depend upon the character of the contents. In some cases it will be paper. In other cases it may be rubber or other pliable material, but at any event it is one which is expendable since one purpose of the construction is to provide a container which need not be cleansed since the interior thereof is never in contact with the contents.

Actually the liner 4| serves somewhat in the way of an inner tube in a tire and it is merely inserted through the opening 30 and held in place by means of the fitting 35 after which it effectively seals the structure by spreading itself over the interior thereof when the contents of the container is put into place.

It will be noted in Fig. 8 that the sections of the container are held together by means of a two piece band clamp 42 whose clamping plates 43 are free to slide between the sides of the channel I 6. When the nuts 44 are tightened they cause the threaded ends 45 of the members 42 to be drawn tightly around the assembled sections. From the following it can be seen that there is provided a container which is not only subject to collapse for storage and transportation when empty, but also is capable of presenting a perfectly clean and usable interior without Washing by the mere insertion of a new liner M.

It will be noted in Fig. 5 that there is disposed between the members 24 and 20 a resilient liner 46 adapted to evenly distribute the clamping action between the cylindrical ends thereof.

In Fig. 7 is shown a modification of the device in which dry ice 4! is stored against the head 25 or 29 by means of a cover 48 which is held in place by means of the screws 49.

I am aware that numerous forms of containers have been constructed in the past and, therefore, do not claim such devices broadly but I do intend to cover all such forms and modifications thereof as fall fairly within the appended claim.

I claim:

A container of the class described consisting of a plurality of arcuate sections uniting to form a complete cylinder, each of said sections having an arcuate channel secured to the outer side thereof at each end and between the ends with their open sides outermost, a second set of channels disposed on the inner side of the sections nels being oflset laterally.
